Abstract:

In the work we present the analysis of the influence of characteristics of fiber-optic communication lines connecting distributed peripheral antenna devices on the accuracy of estimating signal parameters in systems based on spatial correlation processing. The research revealed, that the laser source intensity noise and the optical fiber chromatic dispersion are the main factors limiting the accuracy of measuring the parameters of the analyzed signals. Based on the study we estimated the length of the fiber-optic communication line based on commercially available components, which provides the maximum accuracy in determining the bearing of radio emission sources.
